Finally, we also control the standard of each component and each step in the manufacturing process. A dedicated team of purchasers, engineers, quality inspectors and machine operators works day and night to make sure each component meets the stringent Valley quality requirements. Because our suppliers are positioned in america, we can simply perform random inspections of their services to ensure they are meeting our quality criteria. All major parts are also machined by Valley, providing another level of quality control. A final inspection is conducted by assessment each gearbox before it is shipped. And, to help expand make certain Valley quality, randomly chosen gearboxes are life-tested inside our gearbox testing laboratory.

But, even the best gear design and materials won’t help if the gearbox isn’t sealed from the elements. That’s why Valley runs on the irrigation gearbox patented six-barrier insight and nine-barrier output seal to keep oil in and complications out. To compensate for this longer shaft, unique wheels are used that truly move the center of the tire closer to the gearbox output bearing than the industry regular, reducing the load on the gearbox.

Valley also uses U.S.-made, case-hardened bearings created from ultra-pure steel rather than through-hardened Chinese bearings utilized by others. Case-hardening provides superior wear features while maintaining the internal toughness of the core material. Consequently, Valley bearings possess a 40 percent higher load rating.

The Valley gearbox also has a 52:1 gear ratio. This implies the gearbox uses 4 percent less energy to move the machine through the field, but, more importantly, the design includes a fully recessed tooth actions. With a completely recessed style, the gears keep lubrication oil between your gears longer, reducing friction for increased load capacity and longer life.
